The present invention provides a non-aqueous process for the dyeing of a dyeable material at an elevated temperature by contacting a dyeable material with a dye composition at an elevated temperature in a non-reactive environment. The dye composition temperature and the time of contact between the dye composition and the dyeable material are sufficient to effectuate the dyeing of the material. The dye composition comprises a substantially non-aqueous solvent and a dyestuff.

Non-aqueous process for the dyeing of dyable materials at an elevated

The method of treating a textile fabric comprising cellulosic fibers to produce a modified fabric intermediate from which permanently shaped wearing apparel having an improved dry crease recovery can be made, comprising the steps of: (1) impregnating the material with a cellulose cross-linking reagent selected from the groups consisting of: (a) reaction products of formaldehyde with carboxamides wherein said reaction products contain 2 or 3 N-methylol groups and methyl ethers thereof; (b) compounds having the following generic formula:

Controlling degree of reaction by controlling heat input in cellulose

This invention relates to a process for improving the soil release and wetting properties of a polyester textile material by applying thereto a limited amount of an aqueous solution containing about 0.5 to 2.5% by weight of sodium hydroxide and then contacting the textile material with steam while maintaining a moisture content of at least 35% to remove 0.4 to 2.5% by weight of the polyester. By using this procedure the amount of polyester removed is controlled by the limited amount of sodium hydroxide present while at the same time a substantially uniform product is obtained.
